As a cheese enthusiast and blogger and the author of a yogurt cookbook, I’m never happy to see dairy foods get slammed. Cows have sustained us for millennia, yet they are increasingly under scrutiny for their role in climate change. The New York Times recently published a Q&A-style feature on the environmental impact of our food choices, and I’m sure the takeaway for many readers was, “Eat less cheese.” Some people will go further and ditch dairy foods entirely. I wondered how the many progressive dairy farmer/cheesemakers I know are grappling with these issues so I reached out to one of the industry’s wise men, Andy Hatch.
